CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of co-pending U.S. patent application Ser. No. 14/057,156, filed 18 Oct. 2013 (Agent Docket No. SMPUS1), and is incorporated herein by reference. The present application and the priority application identified above include identical inventorship and ownership.

BACKGROUND

The disclosure relates to the field of load bearing systems.

Generally and in humans, an acromion comprises an outer end of the scapula. A humerus comprises the long bone in the arm extending from the shoulder to the elbow. A clavicle comprises a bone that extends from the sternum to the acromion.

SUMMARY

In one embodiment, a system may include an acromion-socket constructed out of multiple components that are shaped to engage a user's acromion-portion. The system may also include a strap positioned away from the user's neck by the acromion-socket to connect a load to the user.

The acromion-socket may be shaped to also engage a user's upper humerus that is closest to the user's acromion-portion, and the multiple components includes a weight bearing material and at least one of fabric, thread, adhesive, fastener, deformable material, hard member, thermoformed material, webbing, and flexible member. The acromion-socket may be removable from the strap, can be added to the strap, can be positioned anywhere along the strap, positioned by strap tension, and/or integral to the strap.

The load may be carried in front, back, and/or side of the user. The strap crosses a vertical line defined by the user's spinal cord and/or does not cross a vertical line defined by the user's spinal cord.

The acromion-socket shape may be fixed prior to any load bearing. The acromion-socket may be pre-formed by a manufacturer of the acromion-socket to aid in engaging the user's acromion-portion, and the strap may be narrower than the acromion-socket to provide the user reduced heat buildup, increased mobility, reduced chances of snagging, and/or greater ease of use.

The acromion-socket pre-forming may be achieved by material cut pattern, fastening pattern, fabrication process, panel shaping, thermo-forming, and/or material selection. The acromion-socket may maintain the load's weight on the user's acromion-portion during use of the acromion-socket by positioning the acromion-socket on the user's acromion-portion through the cupping of the user's acromion-portion instead of permitting the acromion-socket to slide away from the user's acromion-portion and towards the user's neck.

The acromion-socket may transfer a majority of the load's weight to the user's acromion-portion. The user's acromion-portion may include a portion of the user's deltoid muscle.

Another aspect is a method, which may include engaging a user's acromion-portion with a shaped acromion-socket. The method may also include positioning a load away from the user's neck via the acromion-socket.

The method may further include making the acromion-socket monolithic and/or made of multiple components. The method may additionally include making the acromion-socket removable from a strap, can be added to a strap, can be positioned anywhere along a strap, positioned by strap tension, shaping the acromion-socket by tension, and/or integral to a strap.

The method may also include carrying the load by front, back, and/or side of the user. The method may further include fixing the shape of the acromion-socket prior to any load bearing.

The method may additionally include pre-forming the shape of the acromion-socket by a manufacturer of the acromion-socket to aid in engaging the user's acromion-portion. The method may also include achieving the acromion-socket pre-forming by material cut pattern, fastening pattern, fabrication process, panel shaping, thermo-forming, and/or material selection. The method may further comprise including a portion of the user's deltoid muscle in the user's acromion-portion.

In another embodiment, the system may include an acromion-socket that is shaped to engage a user's acromion-portion, the acromion-socket is designed to carry a load greater than five pounds for over an hour without damaging the acromion-socket, and/or the acromion-socket positions a load away from the user's neck.

In one embodiment, the system includes an acromion-socket to receive a user's acromion-portion. The system may also include a strap positioned by the acromion-socket where the strap connects a load to the user.

The acromion-socket may be shaped to also engage a user's humerus that is closest to the user's acromion-portion. The acromion-socket may be removable from the strap, can be positioned anywhere along the strap, and/or integral to the strap.

The acromion-socket's greatest width is larger than the strap's greatest width. The strap crosses a vertical line defined by the user's spinal cord and/or does not cross a vertical line defined by the user's spinal cord.

The acromion-socket comprises a deformable material that aids in engaging the user's acromion-portion and/or a hard member that aids in engaging the user's acromion-portion. The acromion-socket is pre-formed to aid in receiving the user's acromion-portion. The acromion-socket pre-forming is achieved by material cut pattern, fastening pattern, fabrication process, and/or material selection.

The acromion-socket maintains the load's weight on the user's acromion-portion during use of the acromion-socket by positioning the acromion-socket on the user's acromion-portion through the cupping of the user's acromion-portion instead of permitting the acromion-socket to slide away from the user's acromion-portion and towards the user's clavicle closest to the user's acromion-portion. The acromion-socket transfers a majority of the load's weight to the user's acromion-portion.

DETAILED DESCRIPTION

Embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments are shown. Like numbers refer to like elements throughout.

With reference now to FIG. 1, a load bearing system 10 is initially described. In one embodiment, the system 10 includes an acromion-socket 12 to receive a user's 11 acromion-portion 14. In one embodiment, the acromion-portion 14 comprises the user's 11 acromion, muscles, ligaments, skin, and/or the like. In another embodiment, the acromion-portion 14 comprises the user's 11 acromion, humerus, muscles, ligaments, skin, clothing, and/or the like.

In one embodiment, the acromion-portion 14 comprises at least one of the user's 11 muscles, ligaments, skin, clothing, and/or the like, but excludes the user's acromion. In another embodiment, the acromion-portion 14 comprises the user's 11 humerus, muscles, ligaments, skin, clothing, and/or the like, but excludes the user's acromion. In another embodiment, the acromion-socket 12 includes openings. For example, the openings can provide ventilation, reduced weight, and/or the like.

The system 10 also includes a strap 16 positioned by the acromion-socket 12 where the strap connects a load 15 to the user 11. For example, the load 15 comprises a daypack, messenger bag, backpack, heavy item, bulky article, golf clubs, equipment such as lawn maintenance equipment, an infant carrier (front, back, or side), and/or the like. In one embodiment, the load 15 excludes clothing, garments, and/or the like. In another embodiment, the system 10 excludes the positioning of a user's 11 clothing, garments, and/or the like. The strap 16 can include multiple attachment points to the acromion-socket 12 and/or the load, for instance. In another embodiment, the strap 16 includes multiple straps that connect to the acromion-socket 12 and/or the load 15. In another embodiment, the strap 16 includes an outrigger (not shown) that passes under the user's 11 arm.

In one embodiment, the acromion-socket 12 is shaped to also engage a user's 11 upper-humerus 18 that is closest to the user's acromion-portion 14. In other words, the acromion-socket 12 receives, e.g. cups, the user's 11 acromion-portion 14 as well as the user's upper-humerus 18. In another embodiment, the acromion-socket 12 is removable from the strap 16, can be positioned anywhere along the strap, and/or integral to the strap. For example, the upper-humerus 18 includes the humeral greater tubercle, humeral lesser tubercle, humeral head, surgical neck, deltoid tuberosity, and/or the like.

In one embodiment, the acromion-socket's 12 greatest width 20 is larger than the strap's 16 greatest width 22. For example, the acromion-socket's 12 greatest width while being used by the user 11 is larger than the strap's 16 greatest width at that same point in time.

In one embodiment, the strap 16 crosses a vertical line 24 defined by the user's 11 spinal cord and/or does not cross a vertical line defined by the user's spinal cord. In other words, the strap 16 stays on the side of the acromion-socket 12 and/or crosses over the spinal cord line 24 to the user's 11 other side.

In one embodiment, the acromion-socket 12 comprises a deformable material 19 that aids in engaging the user's 11 acromion-portion 14 and/or a hard member 17 that aids in engaging the user's acromion-portion. For example, the deformable material 19 comprises foam, elastic material, padding, and/or the like, and the deformable material conforms to the user's 11 acromion-portion 14 during use of the acromion-socket 12. In another embodiment, the hard member 17 comprises a plastic cup and/or the like that covers the acromion-socket's 12 side, e.g. top-side, that does not engage the user 11, for instance. In another embodiment, the hard member 17 comprises ribs, plates, and/or the like.

In one embodiment, the acromion-socket 12 is pre-formed to aid in receiving the user's 11 acromion-portion 14. For example, the acromion-socket 12 is sized and/or shaped to cup a user's 11 acromion-portion 14. The acromion-socket's 12 pre-forming is achieved by material cut pattern, fastening pattern, fabrication process, and/or material selection.

The material cut pattern aids in pre-forming the acromion-socket 12 when the panels are joined together, e.g. sewing, bonding, and/or the like, which have curved seams, which results in panel-shaping, for instance. Once the panels are together, they assume a predetermined acromion-socket 12 profile that includes a cavity to receive the user's 11 acromion-portion 14. The fastening pattern aids in pre-forming the acromion-socket 12 when the fasteners, e.g. strap and buckle, hook and loop combinations, and/or the like, are adjusted to provide the pre-formed shape, for example. The fabrication process aids in pre-forming the acromion-socket 12 when an elastic panel is joined to a non-elastic panel, e.g. alternating pattern, to provide a preload and/or post-load shaping to the acromion-socket 12, for instance. The material selection aids in pre-forming the acromion-socket 12 when a wire, hard member 17, panel, and/or the like provide structure to the acromion-socket 12.

In another embodiment, some degree of rotary motion is possible for the user's 11 acromion-portion 14 within the acromion-socket 12. In other words, the user's 11 acromion-portion 14 comprises a ball-like part, e.g. acromion, humerus, muscles, ligaments, skin, clothing, and/or the like, that fits into a ball-like socket, e.g. the acromion-socket 12, and such allows the ball-like part some free movement within the ball-like socket. In another embodiment, the rotary motion is possible for the user's 11 acromion-portion 14 with the acromion-socket 12 due to swivels, flexible members, and/or the like linking the acromion-socket to the strap 16.

In one embodiment, the acromion-socket 12 maintains the load's 15 weight on the user's 11 acromion-portion 14 during use of the acromion-socket by positioning the acromion-socket on the user's acromion-portion through the cupping of the user's acromion-portion instead of permitting the acromion-socket to slide away from the user's acromion-portion and towards the user's clavicle 26 closest to the user's acromion-portion. The acromion-socket 12 transfers a majority of the load's weight to the user's 11 acromion-portion 14.

With additional reference to FIGS. 13-15, in one embodiment, the system 10 includes an acromion-socket 12 constructed out of multiple components that are shaped to engage a user's acromion-portion 14. The system 10 also includes a strap 16 positioned away from the user's 11 neck 23 by the acromion-socket 12 to connect a load 15 to the user. For example, the neck 23 includes the user's 11 trapezius muscle. In another example, the neck 23 excludes the user's 11 trapezius muscle.

In one embodiment, the acromion-socket 12 is shaped to also engage a user's 11 upper humerus 18 that is closest to the user's acromion-portion 14, and the multiple components includes a weight bearing material and at least one of fabric, thread, adhesive, fastener, deformable material, hard member, thermoformed material, webbing, and flexible member. In another embodiment, the acromion-socket 12 is removable from the strap 16, can be added to the strap, can be positioned anywhere along the strap, positioned by strap tension, and/or integral to the strap.

In one embodiment, the load 15 is carried in front, back, and/or side of the user 11. In other words, the load 15 can be carried on the front, back, or side of the user 11. In another embodiment, the strap 16 crosses a vertical line 24 defined by the user's 11 spinal cord (not shown) and/or does not cross a vertical line defined by the user's spinal cord.
